In an interview on Friday in his CNN office, Mr. Zakaria again apologized for what he had called “a terrible mistake.”

“This week has been very important because it has made me realize what is at the core of what I want to do,” Mr. Zakaria said. He said he wanted to “help people to think about this fast-moving world and do this through my work on TV and writing.”

He added: “Other things will have to go away. There’s got to be some stripping down.”
